Event::generic - generic event handling
use Event::generic; $source = Event::generic::Source->new; $w = Event->generic(source => $source, ...); $w = $source->watch(...); $source = $w->source; $w->source($source); $source->event; $source->event($data); $data = $event->data;
This module provides a watcher type within the Event framework. You must understand the architecture of the Event system in order to understand this document.
Event
This module provides a system of reified event sources and watchers watching those sources. Events are generated solely by a method on the event source object. The events may carry arbitrary data to the event handler callbacks. This module is intended for situations where the events of interest are best determined by Perl code.
A reified event source.
A watcher that can watch Event::generic::Source event sources.
Event::generic::Source
A (target) event that can carry arbitrary data.
Creates and returns a new event source.
The invocation of this method is a source event for watchers of the event source. When this method is called, each active watcher of the event source generates a target event. The DATA, if supplied, is copied into the target event objects, from which it can be retrieved using the data() method.
data()
Generates and returns a new watcher, configured to watch this event source. The standard watcher attributes may be specified as arguments. The watcher returned is an ordinary Event::generic, and may be reconfigured to watch a different event source.
Event::generic
The event source to watch. This must be either an Event::generic::Source object or undef. When set to undef, no source is being watched, and the watcher cannot be started.
undef
Returns the data associated with the event, which may be any scalar. This is read-only, and is set by the event source.
